Purpose: To investigate the influence of retinal photocoagulation with an indirect ophthalmoscopy contact lens on corneal endothelial cells.
Methods: Seventeen eyes of 17 patients were evaluated, and corneal endothelial cells were measured twice: just before retinal photocoagulation using an indirect ophthalmoscopy contact lens and 33.2 +/- 10.2 days after surgery.
Results: A statistically significant reduction was found in corneal endothelial cell numbers before versus after surgery (P = 0.0003).
Conclusion: Our results show corneal endothelial cells to be decreased by retinal photocoagulation with an indirect ophthalmoscopy contact lens. When a patient with a low corneal endothelial cell density receives retinal photocoagulation using an indirect contact lens, it is important to be aware of the potential for further loss.

Purpose: To explore the function of cyclopamine in corneal neovascularization and subsequent fibrosis after cornea alkali-burn injury.
Methods: In vivo, mice cornea were injured by NaOH, and then treated with cyclopamine, clodronate liposomes (CLO-LPS), and vehicle of cyclopamine separately by subconjunctival injections. Clinical features were observed and pathological characteristics were examined.
